University of Illinois Coordinated Science Lab (CSL) researchers have demonstrated how to use the commodity storage devices already in conventional computers to save files against ransomware attacks.
The researchers leveraged properties of flash-based storage that currently exist in most laptops, desktops, mobiles, and even Internet of Things devices.
When a file is modified on a computer, rather than deleting the old file version immediately, a solid-state drive saves the updated version to a new location.
If the system is hit with a ransomware attack, the tool can be used to revert to a previous version of the file.
In addition, the tool would help in the case of a user accidentally deleting one of their own files.
